The ability to compute teh distance between two points is important in many situations. In some cases, an estimate based on measurements is sufficent. In other cases greater percision is necesary.
The distance between two points on the same horizontal or vertical line can be found by taking the difference of teh x-or y- coordinate.
Polyhedron- A polyhedron is a closed spatial figure composed of polygons, called the faces of the polyhedron. The intersections of the faces are the edges of the polyhedron. The vertices of the faces are the vertices of the polyhedron.
Parallel Planes- Two planes are parallel if and only if they do not intersect.
A Line Perpendicular to a Plane- A line is perpendicular to a plane at a point P if and ONLY if it is perpendicular to every line in the plane that passes through P
A Line Parallel to a Plane- A line that is not contained in a given plane is parallel to the plane if and ony if it is parallel to a line contained in the plane
Dihedral Angle- A dihedral angle is the figure formed by two half-planes with a common edge. Each half-plane is called a face of the angle, and the common edge of the half-planes is called the edge of the angle.
Masure of a Dihedral Angle- The measure of a dihedral angle is the measure of an angle formed by two rays that are on the faces and that are perpendicular to the edge.
Diagonal of a Right Rectangular Prism- The length of the diagonal, d, of a right rectangular prism is given by d = the square root of l squared + w squared + h squared
(x^1,y^1) and (x^2, y^2) is d=square root of (x^2-x^1)^2+(y^2-y^1)
Distance Formula- D = the square root of (x*2- x*1)*2 + (y*2- y*1)*2
